The purpose of this is to obtain correct fault information by always performing error information collection after collecting fault information.

複数の入出力装置４から構成されている。In recent computer systems, in order to reduce the load on central processing units and input/output processing units and improve performance, computer maintenance equipment is used to recover from failures that occur within the system and collect failure information. In other words, many devices are equipped with a service flow sensor (SVP). An example of such a computer system is shown in FIG. In the figure, the system includes a central processing unit 1, a computer maintenance device 2, an input/output processing device 3, and a plurality of input/output devices 4 connected to the input/output processing device 3.

的に実行されることになる。In such a computer system, a dedicated input/output processing unit recovery command is prepared in the central processing unit 1 for -C to recover from a failure on the input/output processing unit 3 side. This command is issued from the central processing unit 1 to the computer maintenance equipment 2, and in response to the command, the computer maintenance equipment 2
An initialization signal is issued to. Generally, the processing speed of the computer maintenance device 2 is slow, so the failure information collection, failure recovery, and initialization processing of the input/output processing device 3 mentioned above are each queued inside the computer maintenance device 2 and executed asynchronously. will be done.

置３は中央処理装置１に対して異常発生割込みによって
異常発生を報告するとともに、計算機保守装置２に対し
て自装置からの障害情報（ＬＯＧ）の採取を要求する。When a failure occurs on the input/output processing device 3 side, the input/output processing device 3 not only reports the occurrence of the abnormality to the central processing unit 1 using an abnormality occurrence interrupt, but also sends failure information from the own device to the computer maintenance device 2. (LOG) is requested.
その要求は、一旦計算機保守装置２内部の処理キューに
入れられる。The request is temporarily placed in a processing queue inside the computer maintenance device 2.
すなわちエンキューされる。In other words, it is enqueued.

ＬＯＧ”′としてエンキューされる。FIG. 7 is an explanatory diagram of a conventional example of an input/output processing device initialization method using a processing queue in a computer maintenance bag. In the figure, a request to collect LOG (fault information) from the input/output processing device 3 is sent to the processing queue 5 in the computer maintenance device 2.
It is enqueued as LOG"'.

し、その処理を行う。On the other hand, the central processing unit 1 detects an abnormality in the input/output processing unit 3 and issues an input/output processing unit recovery command, that is, a reset (RST) command in the abnormality processing routine. The instruction is actually enqueued into the processing queue 5 in the computer maintenance device 2 as an input/output processing unit initialization request (RST). The computer maintenance device 2 dequeues, that is, takes out the requests enqueued in the processing queue 5 one by one, and processes the requests.

処理装置３からの障害情報の採取が後で実行されること
があるという問題点があった。In the conventional input/output processing device initialization method shown in FIG. 7, that is, the method of taking out and processing requests enqueued in the processing queue 5 in the computer maintenance device 2, the execution order of the processing queues is undefined. When a failure occurs in the input/output processing unit 3, the input/output processing unit initialization request from the central processing unit 1, that is, the RST command, is executed first, and the collection of failure information from the input/output processing unit 3 is executed later. There was a problem that sometimes.

優先度が最も高いために入出力処理装置３の初期化が先
に行われてしまうという場合もあった。In other words, if the processing queue 5 is enqueued, for example, by being enqueued to an empty part of the processing queue, and on the other hand, requests within the processing queue are executed from the head of the queue. , the input/output processing device 3 may be initialized first,
In such a case, the input/output processing device 3 has already been initialized when the failure information is collected, and the collected failure information is meaningless. Furthermore, even if the processing queue 5 is enqueued in such a way that failure information is collected first, the input/output processing device 3 is initialized first because processing by the central processing unit 1 generally has the highest priority. In some cases, they were lost.
本発明は、入出力処理装置の初期化を必ず障害情報の採

As shown in the figure, in a computer system consisting of a central processing unit I, a computer maintenance device 2, an input/output processing device 3, and a plurality of input/output devices 4 connected to the input/output processing device 3, the input/output processing device 3 side FIG. 3 is a functional block diagram of an initialization method for the input/output processing device 3 when a failure occurs in the input/output processing device 3.

Next, in step 8, the input/output processing device 3 notifies the central processing unit 1 that the initialization process has been completed, and the initialization of the input/output processing device 3 is completed.

ュー５にエンキューされる。In the figure, when a failure occurs on the input/output processing device 3 side, the input/output processing device 3 is transferred to the computer maintenance equipment 52 as 6.
Requests for collection of failure information (LOG) and self-device initialization (RST) are issued, and the requests are enqueued in the processing queue 5 in the computer maintenance device 2.
そして図示しないが、中央処理装置１へも入出力処理装
置３から障害発生が、例えば割込みとして通知される。Although not shown, the central processing unit 1 is also notified of the occurrence of a failure by the input/output processing unit 3, for example, as an interrupt.

終了が通知される。A reset command from the central processing unit 1 is sent to the input/output processing unit 3.
Before or after inputting the error information to the input/output processing device 3, collection of failure information from the computer maintenance device 2 to the input/output processing device 3 and initialization of the input/output processing device 3 are performed in step 7. Finally, the input/output processing unit 3 notifies the central processing unit 1 of the completion of the initialization process at step 8.

理装置１はリ七ソ１・終了を知ることができる。Even if a reset command is manually inputted from the central processing unit I to the input/output processing unit 3 before the input/output processing unit 3 is initialized by the computer maintenance equipment 2 in step 7, the input/output processing unit 3 does not respond to that command. No processing is performed, and when the central processing unit 1 is notified of the end of the initialization process in step 8, the central processing unit 1 can know that the resetting process 1 has ended.
以上のように、本発明では、入出力処理装置３の正しい
障害情報（ＬＯＧ）の採取の後に入出力処理装置３の初
期化が行われることになる。As described above, in the present invention, the input/output processing device 3 is initialized after correct failure information (LOG) of the input/output processing device 3 is collected.

Upon receiving the command, 3a requests the SVP 12 to initialize (RESET) the input/output processing device 13b at (3), and the request is enqueued in the processing queue 12a.

になる。When the input/output processing device 13b is initialized by the computer maintenance device SVP 1 2, the hardware is actually reset in step 2, and completion of initialization is reported to the C H P 1 3a in step 2. Upon receiving this report, the CHP 13a notifies the CPU 1 of the completion of the reset in step 2 via an interrupt. In other words, on the CPU II side, the reset command issued at ■ has finished at that point, and the CHU13a
The reset completion notification from will be transmitted as an interrupt.
